Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate.

FIG. 1 is a perspective view showing the configuration and usage of the solar cell module 100 according to the first embodiment. FIG. 2 is a plan view of the main part of the solar cell module 100. The solar cell module 100 is a portable solar cell module and includes a solar cell power generation unit 102 and a connection member 104.

The solar battery power generation unit 102 includes a solar battery cell 110, a protection member 120, and a terminal part 126. The solar battery cell 110 has a substrate for forming a photoelectric conversion element and a photoelectric conversion element formed on the substrate. The protection member 120 holds the solar battery cell 110 therebetween. The protective member 120 is formed by laminating the solar battery cell 110 between two films such as a laminate film. Thereby, the protection member 120 protects both the front surface and the back surface of the solar battery cell 110 and has at least one side. The surface of the solar battery cell 110 is a surface that receives light. The terminal portion 126 is a terminal for taking out the output of the solar battery cell 110. The terminal portion 126 is provided on the outer periphery (one side) of the protection member 120, and is connected to the solar battery cell 110 via the lead lead wiring 124 provided on the protection member 120.

The connecting member 104 supplies the output of the solar battery cell 110 to the external electronic component 200. In the example shown in the figure, the electronic component 200 is an AC adapter of an electronic device such as a portable computer. The connecting member 104 includes a covering member 130 and an output connecting portion 140. The covering member 130 covers at least the periphery of the terminal portion 126 in the outer periphery of the terminal portion 126 and the protection member 120. The covering member 130 is formed by, for example, a resin mold. The covering member 130 preferably does not have flexibility.

The output connection part 140 includes an output wiring, a part including one end 142 of the output wiring is located in the covering member 130, and the other end 144 which is an output side end of the output wiring is a covering member. It is located outside 130. One end 142 of the output connection portion 140 is connected to the terminal portion 126, and is connected to the solar battery cell 110 via the terminal portion 126 and the lead wire 124. The other end 144 of the output connection unit 140 has a terminal for connecting to the electronic component 200. This terminal is a two-core connector that can be connected to the power adapter, for example, a terminal that complies with any standard defined in IEC standard 60320 / J60320. The electronic component 200 is an AC adapter of a portable electronic device 220, for example. The electronic device 220 is, for example, a notebook personal computer, but may be another electronic device.

In this embodiment, the protection member 120 is rectangular or square, and the terminal portion 126 is provided on one side 121 of the protection member 120. In this case, as shown in FIG. 2, the covering member 130 is preferably provided over the entire length of one side 121 of the protective member 120. The output connecting portion 140 preferably extends outside the covering member 130 from an end surface 132 (shown in FIG. 1) that intersects one side 121 of the protective member 120 in the covering member 130.

Moreover, the solar battery cell 110 may be a thin film solar battery having flexibility or a solar battery not having flexibility. When the solar battery cell 110 has flexibility, the solar battery cell 110 is a thin film solar battery in which a photoelectric conversion layer is formed on a flexible substrate, for example.

Moreover, when the solar battery cell 110 has flexibility, it is preferable that the protection member 120 also has flexibility. When the protective member 120 is formed of a front surface side protective member and a back surface side protective member, the front surface side protective member may be polyethylene tetrafluoroethylene (ETFE), polytrifluorinated ethylene, polyvinyl fluoride, or the like. The fluororesin film is used. In addition to the above, a thin metal plate such as a steel plate, an aluminum plate, and a stainless plate, a plastic plate, an FRP plate, or the like can be further used as the protective member on the back side.

In the present embodiment, the solar battery power generation unit 102 includes a plurality of solar battery cells 110 connected in series. In this case, it is preferable that the output voltage is higher than the minimum voltage (for example, 90 V) of the commercial AC power supply. In the example shown in this figure, the solar cells 110 are connected in series by a wiring 122. The output can be taken out from the terminal portion 126 by the lead lead wiring 124. The lead lead wiring 124 is insulated and covered with the protective member 120 and the terminal portion 126.

FIG. 10 is a perspective exploded view showing the configuration of the solar cell power generation unit 102. The solar cell power generation unit 102 is a SCAF (Series Connection through Aperture on Film) type thin film solar cell. Specifically, the solar battery power generation unit 102 includes a solar battery cell 110 including a substrate 310, a photoelectric conversion element 115, a connection electrode layer 314, a lead lead wiring 124 a including a conductive foil lead, and a protection member 120. Prepare.

The substrate 310 is made of insulating material such as polyimide, polyamide, polyimide amide, polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyetherimide (PEI), polyetheretherketone (PEEK), and polyethersulfone (PES). It is a sex substrate.

The photoelectric conversion element 115 has a configuration in which a lower electrode layer 111, a photoelectric conversion layer 112, and a transparent electrode layer 113 are laminated in this order on one surface of a substrate 310. The photoelectric conversion layer 112 is formed of, for example, a microcrystalline silicon layer or an amorphous silicon layer. A connection electrode layer 314 is formed on the opposite surface (back surface) of the substrate 310. Then, a plurality of divided photoelectric conversion elements 115 and connection electrode layers 314 are arranged side by side to constitute the solar battery cell 110 as a whole.

The photoelectric conversion element 115 is arranged as a plurality of divided blocks on one surface of the substrate 310, and the connection electrode layer 314 is arranged as a plurality of divided blocks on the opposite surface of the substrate 310. In plan view, the block of the photoelectric conversion element 115 and the block of the connection electrode layer 314 are displaced from each other, and are arranged so that the other overlaps the gap between the blocks.

A plurality of through holes, which are current collecting holes 312, are arranged in the solar cell 110, and the transparent electrode layer 113 and the connection electrode layer 314 are electrically connected by a conductive film provided on the inner wall of the current collecting hole 312. Connected to.

Further, a connection hole 316 is provided at a location where the transparent electrode layer 113 is not partially formed, and the lower electrode layer 111 and the connection electrode layer 314 are provided on the inner wall of the connection hole 316. They are electrically connected by a conductive film.

The current collecting hole 312 and the connection hole 316 are connected to another connection electrode layer 314 block adjacent to the divided connection electrode layer 314, and the connection electrode layer to which the connection hole 316 is connected. Since the current collection holes 312 of the blocks of the adjacent photoelectric conversion elements 115 are connected to the block 314, the adjacent blocks of the photoelectric conversion elements 115 are connected in series.

Such a SCAF type configuration can realize multi-stage series connection in a small size while obtaining sufficient insulation, so that a high voltage (about 100 V or more) can be obtained from a small solar cell module.

The lead lead wire 124a is, for example, a copper foil lead wire, and is led out of the substrate 310 from the other surface (the lower surface in FIG. 10), and the output of the solar cell 110 is sent to the terminal portion 126 described above. introduce. Specifically, the two lead lead wires 124 a are connected to blocks of connection electrode layers 314 located at both ends of the substrate 310.

Further, a portion of the lead lead wiring 124a that is led out of the substrate 310 is sandwiched between the protection member 120, that is, the protection member 120a on the front surface side and the protection member 120b on the back surface side. In such a structure, the

protection members

120a and 120b are insulative at least on the surface in contact with the lead wire 124. For this reason, even if the output voltage of the lead wire 124 is high, insulation can be ensured.

FIG. 3A is a cross-sectional view taken along the line AA ′ of FIG. In the example shown in FIG. 3A, the covering member 130 of the connection member 104 is in contact with a part of the end face and the surface of the solar cell power generation unit 102 on one side 121 of the protection member 120 of the solar cell power generation unit 102. The solar cell power generation unit 102 is not in contact with the back surface. That is, in the example shown in this drawing, the covering member 130 covers the upper surface and the side surface of one side 121 of the protective member 120.

Note that the covering member 130 may have another shape. For example, as shown in FIG. 3B, only one end surface may be in contact with one side 121 of the protection member 120. Moreover, as shown in FIG.3 (c), the structure pinched from the upper and lower sides in the one side 121 of the protection member 120 may be sufficient. In the embodiment shown in FIG. 3C, the covering member 130 covers the upper surface, side surface, and lower surface of one side 121 of the protective member 120.

Next, functions and effects of this embodiment will be described. In the present embodiment, the lead-out lead wiring 124 is a protective member 120 and the terminal portions 126 (126a, 126b) are insulatively coated with a covering member 130, respectively. For this reason, even if the output of the solar cell power generation unit 102 is high, it is possible to ensure the insulation of the lead wire 124. Therefore, the output of the solar cell power generation unit 102 can be supplied to the power adapter as it is.

Further, the connection member 104 for taking out the output of the solar cell power generation unit 102 is provided only on a part of the outer periphery of the solar cell power generation unit 102. For this reason, the solar cell module 100 can be reduced in size. Further, by having the connection member 104, the solar cell module 100 can be carried without touching the solar cell power generation unit 102. This effect becomes remarkable when the covering member 130 sandwiches the protective member 120 from above and below as shown in FIG. Therefore, the portability of the solar cell module 100 can be improved.

Further, when the protective member 120 of the solar cell power generation unit 102 is rectangular or square, the solar cell module 100 can be easily held by providing the covering member 130 of the connecting member 104 over the entire length of one side 121 of the protective member 120. Further, when the output connecting portion 140 of the connecting member 104 extends outward from the end surface 132 that intersects one side 121 of the protective member 120 of the covering member 130, the output connecting portion 140 can be connected to a human hand when the connecting member 104 is held. Interference can be suppressed.

Further, when both the solar battery cell 110 and the protective member 120 of the solar battery power generation unit 102 have flexibility, when the solar battery module 100 is carried, the solar battery module 100 is sunlit around the covering member 130 of the connecting member 104. The battery power generation unit 102 can be wound up. For this reason, the portability of the solar cell module 100 is further improved.

Further, the other end 144 of the output connecting portion 140 of the connecting member 104 has a two-core connector that can be connected to a power adapter of an electronic device, for example, a terminal that complies with any standard defined in IEC 60320 / J60320. In this case, the other end 144 can be directly inserted into an AC adapter attached to the portable electronic device 220 such as a notebook computer. Accordingly, since the output of the solar cell module 100 becomes higher than the minimum voltage of the commercial AC power supply, the power source of the electronic device (used as a power source for charging) can be used only by the solar cell module 100 without using another power adapter. Can be used as well). In particular, when an electronic device is carried and there is no commercial AC power source nearby, the merit of using the solar cell module 100 as a power source for the electronic device becomes significant.

The weight 141 sandwiches the protective member 120 from above and below at the side 123, for example, similarly to the covering member 130.

Also in this embodiment, the same effect as that of the first embodiment can be obtained. Further, when both the solar battery cell 110 and the protection member 120 have flexibility, the solar battery power generation unit 102 can be wound around the covering member 130 and carried. In this case, the solar battery power generation unit 102 There is a possibility that a curl will be attached to. On the other hand, in this embodiment, since the solar cell power generation unit 102 is provided with the weight 141, the solar cell power generation unit is used when the solar cell module 100 is used even if the solar cell power generation unit 102 has a curl. 102 can be easily expanded.
